My Dewalt 12.5 inch planer skips or bits in approximately every 6 to 8 inches while planing. The belt is new the blades are new, the bushings are good and the feed rollers are clean and in good shape. Do have any ideas what to check next? Thank you. Mike

Clean the machine inside usually there is a line or square wood cross and
use a dust extractor with an induction motor, high enough capacity

At least 12"

If you're looking at the planer from the infeed side, there's a belt guard on the right side of the head. Remove it and check the condition of the drive belt. If it's broke the motor will spin without powering the cutterhead and feed rollers. The drive belt is still available as part number 22-563 on sites like http://servicenet.dewalt.com/ and www.ereplacementparts.com. Just put your model number in their search box and find the drive belt in the breakdown.

Common problem. As long as the chip/dust doesn't impede the dust collection or interfere with anything else, it's normal, and to be expected.

this is normal with all planers, when you feed the board in the planer there are two feed roller one on each side of the knives so you get uneven pressure on the board at the start and at the end of the board .when planing boards for a project always add 10"inches or more extras then cut to lenght after planing to thickness required. never cut boards to length before planing .

Use a backing board, such as high grade 3/4 inch plywood under the board you are planing, and you should be able to get down to 1/16, depending on the stability of the board you are planing. Take light cuts and flip it over to cut on both sides. Sounds like you might be making a guitar? Good luck.

I'm having the same problem, I replaced the drive chain & sprockets but the problem has reapeared.
